Coin, Shield, and Spelltheif should have an active usable on turrets that grants 2gps when it drops.

Basically any support starting item would have this active until it is combined or upgraded, and it would last for the entire match, that way when you are the unlucky team to instantly lose bot turret you are not completely... you know...

On the note of improving Supp Qol, what is these starting items each had an additional passive which reduced the total cost of sightstone by roughly 100g? Just a shot in the dark.
